MRI of Adhesions and Small Bowel Obstructioncute emergency with pending ileus is CT. Nevertheless, MRI can provide superior information. Besides the classical signs of obstruction with distended bowel loops and transition points, its potential to detect visceral slide using functional cine MRI has been proven.

MRI of the Gastrointestinal Tract: Coils, Sequences, Techniquesr coils need to be purpose-designed for adequate coverage and efficient to provide good signal. Increasingly, designs take account of parallel acceleration techniques, which can improve volume coverage and temporal resolution. Conventional sequences are still used where motion artifacts are limited

MRI of the Gastrointestinal Tract at High-Field Strengthues need to be addressed and a direct transition of sequences used at 1.5–3 T is not possible. The main constraints in 3 T imaging are related to changes in tissue . and . relaxation parameters, susceptibility artifacts, changes in efficiency of contrast agents, chemical shift artifacts, B1-inhomoge

Contrast Media for MRI of the Gastrointestinal Tracte the relaxation rates of water protons in areas where these agents are distributed. The first generations of systemic, intravenous contrast media are unspecific in action owing to their distribution in the extracellular compartments. The newer agents are more specific and are limited to anatomic ta

MRI of Upper GI Tract Motilityo examine the oropharynx and cervical esophagus in patients who are at risk for aspiration due to swallowing difficulty. Because of the drawback of ionizing radiation exposure, repeated evaluation, especially in children, can be problematic..Endoscopy is limited to the evaluation of the superficial
